Encrypted messaging system inside container

The crypto container works the following way

• You write and save messages
• The messages gets encrypted into container
• The container gets syncronized with remote container on remote drive (currently only flash drives are supported, but in the future other modules can be written (SSH or Exif ...)
• The messages inside container gets checked and decrypted

The cc systems works in console mode All messages gets viewed and edited in editor (usualy vim or nano) CC uses two encryption algorithms: RSA-4096 and Blowfish. RSA - for signing public and private messages and for Blowfish key encryption Blowfish - for private messages encryption

Instalation

• git clone https://github.com/Alex014/CryptoContainer.git
• pip install pycrypto
• pip install rsa
• python cc.py - View help page
• python cc.py U+user1 - generate user user1
• python cc.py Uuser1 - select user user1
• python cc.py C+container1 - generate container1
• python cc.py Ccontainer1 - select container1
• python cc.py Fremote=/run/media/user/DDD/+upload=/run/media/user/DDD/+editor=nano - remote: remote dir to scan, upload: dir to upload containers, editor - nano

python3 and pip3 in Ubuntu

Saving and synchronizing

• python cc.py C@ - saving current container
• python cc.py C# - uploading current container on flash drive
• python cc.py C^ - download and synchronize fresh copies of all containers
• P* and M* commands to view PUBLIC and INBOX messages

Comands

• C: container

  • cc.py C - display all local containers
  • cc.py Ccontainer_name - select container container_name
  • cc.py C+container_name - generate new container
  • cc.py C-container_name - delete container
  • cc.py C@[container_name] - save container_name or current container if no container name given
  • cc.py C?container_name - display information about container_name
  • cc.py C^ - syncronize all containers
  • cc.py C#[container_name] - upload container_name or current container if no container name given

• U: user and users

  • cc.py U - display all local users
  • cc.py Uuser_name - select user user_name

  • cc.py P= - edit new public message (generate if it does not exist)
  • cc.py P- - delete your last public message
  • cc.py P* - view all decrypted public messages in editor (** - inverted view)

• M: messages from user to user

  • cc.py M - display all local private messages
  • cc.py M+[username+subject+reply_to_message] - generate new private message to username with subject (username and subject are optional if none given you will be prompt to select them) reply_to_message - signature of message you want to reply to (it must be message to you, type 'cc.py M*' to view all your decrypted messages), also optional
  • cc.py M+[username+subject+%2020-06-23+15:02:18] - generate new private message to username with subject and reply to message sent to you from username at 2020-06-23+15:02:18
  • cc.py M= - edit private message (selection mode)
  • cc.py M- - delete private message (selection mode)
  • cc.py M* - view all decrypted private messages in editor (** - inverted view)

• S: status - display information about current container and current user

• F: configuration - view or set configuration options

  • cc.py F - display all configuration options
  • cc.py Fcontainer=container1+editor=vim
  • passable configuration options: container, user, editor, remote, upload
    • container: current container
    • user: current user
    • editor: editor for editing messages
    • remote: remote path to search for remote containers
    • upload: remote path to upload the current container
